Bosch 13664 oxygen sensor for the 2001-2002 Jeep Wrangler 4-cylinder 2.5L, the 2001-2003 Wrangler 6-cylinder 4.0L, the 2003-2004 Wrangler 4-cylinder 2.4L and other vehicles measures oxygen in the exhaust and sends air-fuel-ratio readings to the ECU. This Bosch O2 sensor is a heated, switching-type unit that helps hold combustion stable and reduce emissions.
A check engine light, rough idle or poor fuel economy can mean an oxygen sensor is wearing out. A leak in the exhaust, a vacuum leak, worn spark plugs or damaged wiring can be behind those signs too, so find the cause before you buy.
Listed for a wide range of Dodge and Jeep models, it is also an oxygen sensor for the 2001 Dodge Ram 1500 V8 5.9L and the 2002-2003 Ram 1500 V6 3.7L, and for the 2001-2003 Jeep Grand Cherokee 6-cylinder 4.0L. If your vehicle isn't named here, look up its year and engine on the Buyer's Guide tab.
